Solution Overview

Problem

Conventional guide rail systems for pneumatic vacuum elevators cause vibration and generate friction and noise during cabin movement, leading to user anxiety and suboptimal performance.

Innovation Solution

A guide rail-pillar system with a curved structure extruded from the guide rail pillar, featuring grooves for a covering sheet and ribs connecting the pillar to a base ring, which stabilizes and guides the cabin's vertical movement while reducing friction and noise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If conventional guide rail with wheels is used for cabin movement, then the cabin can be guided vertically, but vibration is caused which creates user anxiety

Engineering Contradiction:
Improvecabin movement stabilityVSAvoidvibration
Core Design Contradiction:
Stability of the object's compositionVSObject-affected harmful factors

Solution Approach 1:

The invention extracts and eliminates the wheel component from the guide rail system. By removing the wheels that cause vibration, the patent replaces them with a direct guide rail-pillar contact system where the cabin is guided along the pillar surface without rotating elements, thereby eliminating the vibration source while maintaining guidance function

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention substitutes the mechanical wheel-based guidance system with a direct surface contact guidance system. The curved structure on the guide rail pillar creates a smooth contact surface that guides the cabin through frictionless or low-friction contact, replacing the mechanical wheel rotation mechanism with a streamlined sliding or rolling contact that eliminates vibration

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If conventional guide rail mechanism is used, then the cabin can move up and down, but friction is generated during motion

Engineering Contradiction:
Improvecabin movementVSAvoidfriction
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The invention applies curvature to the guide rail pillar surface, creating a curved structure that optimizes the contact geometry between the guide rail and the cabin. This curved surface distributes the contact pressure more evenly and reduces friction by creating a more favorable contact area, allowing smoother cabin movement with reduced energy loss

Inventive Principle:
Principle #14Spheroidality (Curvature)

3Reliability

If conventional guide rail mechanism is used, then the cabin can be supported during motion, but noise is generated

Engineering Contradiction:
Improvecabin supportVSAvoidnoise
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The invention removes the noise-generating components of the conventional guide rail system, specifically the wheels and their associated mechanical joints. By extracting these elements and replacing them with a streamlined guide rail-pillar contact system, the vibration and noise are eliminated while the curved structure provides continuous support and guidance

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention replaces the noisy mechanical wheel-and-rail interaction with a quieter curved surface contact system. The smooth curved structure on the guide rail pillar creates a more serene operational environment by eliminating the mechanical clicking and grinding noises associated with conventional wheel-based systems

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
